Generating a hash value from a vector representing a data object |
摘要 |
To generate at least one hash value for a feature vector that represents a data object, a discrete orthogonal transform is applied on a second vector produced from the feature vector. Applying the discrete orthogonal transform on the second vector produces a third vector. At least one value is selected from the third vector to produce the hash value. The at least one hash value is used to perform an action. |
